How can I share emails between my email account and my spouse's?

Solution

If you want to openly share all your emails with another person, you can do so while still having two separate accounts. It is not necessary for you to share one account. Gmail has a feature that allows you to check all your emails from multiple accounts (even from different email providers) through one Gmail account. This is called the “Mail Fetcher” feature, which first imports all your old emails from other accounts to a Gmail account, and then continues to “fetch” all the emails that the other email accounts receive. In this way, two people can technically have two email addresses while having complete equal access to each other’s emails.
